Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart of a screen brightness adjusting method shown in an embodiment of the present disclosure, which is applied to a terminal including a display screen, where the terminal includes a plurality of optical sensors, and as shown in fig. 1, the screen brightness adjusting method includes the following steps:
s11, determining the actual light emitting brightness of the light source according to the brightness value of the light source detected by each optical sensor;
and S12, adjusting the display brightness of the display screen according to the actual light emitting brightness.
In an embodiment of the present disclosure, a terminal device includes: a mobile device and a stationary device; the mobile device includes: a mobile phone, a tablet computer or an intelligent sound box with a display screen. The stationary device includes, but is not limited to, a Personal Computer (PC).
The terminal equipment comprises a display screen which can display image frames. Still be provided with light sensor in the terminal, light sensor can set up the below at the display screen, can turn into the signal of telecommunication with the ambient light that sees through the display screen to make the terminal can be according to the signal of telecommunication and confirm ambient light brightness. For a full-screen terminal, a light sensor disposed below a display screen detects ambient light by detecting light transmitted through a space gap between display units.
As previously mentioned, the optical sensor is limited to the field of view (field angle) and the sensed light intensity value may be smaller than the true value. The severity of this problem is exacerbated for full-screen terminals. The reason is that the field angle of the optical sensor placed under the screen is smaller, and the actual application is only about 45 degrees, so that the actual light intensity at the top and the back of the mobile phone may not be sensed, and the light intensity detected by the optical sensor may not be accurate enough.
Fig. 2 is an exemplary view of the viewing angle of an optical sensor under a screen in an embodiment of the disclosure, as shown in fig. 2, taking a mobile phone as an example, the viewing range of the optical sensor under the display screen of the mobile phone is about 0 to 45 degrees.
Typically, the optical sensor will sense the exact light intensity if the terminal is directly below the light source. On the contrary, if there is an included angle between the light source and the optical sensor, and the included angle is too large and even exceeds the visual field range of the optical sensor, the sensing capability of the optical sensor will decline by more than 50%, resulting in a problem of small measurement. In the disclosed embodiment, the position of the light source relative to the terminal refers to the position of the light source relative to the field angle of the optical sensor in the terminal.
Fig. 3 is a first exemplary diagram illustrating positions of the light source and the optical sensor according to the embodiment of the disclosure, as shown in fig. 3, the light source is at the exact center of the field angle of the optical sensor, and the data measured by the optical sensor is close to the real value. Fig. 4 is a second exemplary diagram illustrating positions of the light source and the optical sensor in the embodiment of the disclosure, as shown in fig. 4, the light source is outside the field angle range of the optical sensor, and the data measured by the optical sensor is smaller than the true value.
Fig. 5 is an exemplary graph of light intensity sensed by an optical sensor in an embodiment of the disclosure, where an abscissa represents a position of a terminal with respect to a light source and an ordinate represents a light intensity value sensed by the optical sensor, as shown in fig. 5. Fig. 5 includes 2 curves of the light intensity sensed by the optical sensor, and it can be seen from the trend of the 2 curves that the light intensity sensed by the optical sensor is larger in the range of plus or minus 30 degrees, and the angular deviation exceeds this range, and the larger the deviation is, the smaller the light intensity sensed by the optical sensor is. It should be noted that the inconsistency of the curves of the light intensities sensed by the 2 optical sensors in the terminal may be caused by the difference of the positions of the 2 optical sensors.
As can be seen from the above, the intensity of light detected by the optical sensor may not accurately reflect the actual situation, and thus the brightness of the display screen is adjusted based on the ambient light detected by the optical sensor, and there may be a deviation in the adjustment. For example, the adjustment of the screen brightness is dark, which affects the reading experience of the user.
In this regard, the present disclosure proposes a screen brightness adjustment method, in step S11, determining actual light emission brightness of a light source according to brightness values of the light source detected by a plurality of optical sensors, and then in step S12, adjusting display brightness of a display screen based on the actual light emission brightness of the light source.
In one embodiment, the light source comprises: a point light source or a line light source.
In the embodiments of the present disclosure, the point light source or the line light source refers to light emitted by an electronic device that can emit light, and does not include light emitted by sunlight. This is because the radiation range of sunlight is wide and the light intensity is uniform in any direction, and therefore, the problem of detection variation due to the limitation of the angle of view of the optical sensor does not occur. The radiation range (irradiation area) of the point light source or the line light source is limited because there is a problem that the optical sensor is caused to detect a deviation.
In the embodiment of the present disclosure, when the actual light emission luminance of the light source is determined according to the luminance values of the light source detected by the plurality of optical sensors, for example, considering that the optical sensors make the sensed light intensity value small due to the field angle limitation, in one embodiment, the maximum value among the luminance values of the light source detected by the plurality of sensors may be taken as the actual light emission luminance to reduce the deviation. In another embodiment, the average value of the luminance values of the plurality of optical sensor detection light sources may be multiplied by a predetermined coefficient as the actual light emission luminance. The predetermined coefficient may be a value set to be suitable for most cases, for example, a predetermined coefficient value of 1.3, based on a curve such as that shown in fig. 3.
In the embodiment of the disclosure, after obtaining the actual light emitting brightness of the light source, the terminal may adjust the display brightness of the display screen according to the actual light emitting brightness. For example, when the ambient light brightness information is high, the display brightness of the display screen can be increased; when the ambient light brightness information is very low, the display brightness of the display screen can be adjusted to adapt to human eyes of a user.
It can be understood that, according to the display screen brightness adjusting method and device, the brightness value of the light source detected by the optical sensors in the terminal is utilized to determine the actual brightness of the light source and then adjust the display brightness of the display screen, so that the adjusting accuracy can be improved, and the user experience is improved.
In one embodiment, the determining the actual light-emitting brightness of the light source according to the brightness value of the light source detected by each optical sensor includes:
determining the actual light emitting brightness of the light source according to the brightness value detected by each optical sensor, the preset position relation among the optical sensors and the preset functional relation; the preset functional relationship represents a mapping relationship between an included angle between the light source and the terminal, actual luminous intensity of the light source and a brightness value acquired by the optical sensor.
In the embodiment of the present disclosure, when the actual light-emitting luminance of the light source is determined according to the luminance value of the light source detected by each optical sensor, the predetermined position relationship and the preset functional relationship between each optical sensor may also be combined.
Wherein the predetermined positional relationship between the optical sensors is characterized by a correlation between the field angle orientations of the optical sensors. Taking two optical sensors as an example, if the position between the two optical sensors is vertical, the field angle of one optical sensor may face the display screen, and the field angle of the other optical sensor faces the frame of the terminal, such as the top of a mobile phone; if the position between the two optical sensors is parallel, the field angles of the two optical sensors may both face the display screen. Of course, the present disclosure may have three or more optical sensors, and the positions between the respective optical sensors are predetermined in advance.
In this embodiment, the preset functional relationship may be characterized by the following equation (1):
L*＝f(L,θ) (1)
wherein, L represents the actual luminance brightness of the light source, theta represents the included angle between the light source and the terminal, and L represents the brightness value collected by the optical sensor.
It should be noted that the preset functional relationship of the present disclosure can be obtained by fitting the following experimental data: when the light source is at the +/-90-degree position of the optical sensor, the light sensing capacity of the optical sensor is 0; when the light source is right above (0 degree) the optical sensor, the light sensing capability is 100 percent, namely the actual light emitting brightness of the light source can be correctly detected; when the light source is at the 45 deg. position of the optical sensor, the light sensing capability is halved. And obtaining a curve corresponding to the functional relation based on the data, namely a standard FOV curve.
In this embodiment, since the brightness values detected by the respective optical sensors are known and the predetermined positional relationship between the respective optical sensors is known, the actual light emission luminance of the light source can be obtained by establishing the equation system based on the above formula (1).
It can be understood that, in the present disclosure, the calculation amount is small, and it is simple and convenient, based on the above manner of constructing the equation set to obtain the actual light-emitting brightness of the light source.
In one embodiment, the terminal comprises a first optical sensor and a second optical sensor, wherein the first optical sensor is positioned below the display screen, and the angle of view of the first optical sensor faces to the display screen; the second optical sensor is close to a frame of the terminal, and the field angle of the second optical sensor faces to the frame.
In this embodiment, the terminal includes two optical sensors, and based on the foregoing description, if the viewing angle of the first optical sensor is oriented toward the display screen and the viewing angle of the other optical sensor is oriented toward the bezel, the position between the two optical sensors is perpendicular. FIG. 6 is a diagram illustrating an exemplary position of the light source relative to the field angle of each optical sensor in the embodiment of the disclosure, where the angle of the light source relative to the first optical sensor under the display screen is θ as shown in FIG. 6 1 The angle of the light source relative to the second optical sensor at the top of the terminal is theta 2 . As can be seen from the figure, θ 1 And theta 2 Is approximately 90 degrees. In fig. 6, θ represents 3 The angle between the terminal and the ground level is indicated.
Based on the above fig. 6 and equation (1), if the first optical sensor detects light intensity as L1 and the second optical sensor detects light intensity as L2, then an equation system can be established: l1= f (L, θ) 1 )，L2＝f(L,θ 2 ) Wherein θ 1 +θ 2 =90 °. Since L1 and L2 are known, θ 1 And theta 2 If the angular relationship of (a) is known, L, i.e., the actual light emission luminance of the light source, can be obtained.
In one embodiment, the terminal further includes an angle sensor therein, and the method further includes:
determining a first included angle between a plane where a display screen of the terminal is located and the ground horizontal plane through the angle sensor;
determining a second included angle between the light source and the terminal according to the brightness value detected by each optical sensor, the preset position relation among the optical sensors and a preset function relation;
establishing a light sensation model according to the first included angle, the second included angle and the actual brightness of the light source; the light sensation model is used for determining the actual light emitting brightness of the light source according to the position of the light source.
In this embodiment, the terminal may further include an angle sensor, such as a gyroscope, for detecting a first angle between a plane where the display screen of the terminal is located and the ground level, i.e. θ in fig. 6 3 I.e. the tilt angle of the terminal.
In addition, the present disclosure may also determine a second angle between the light source and the terminal based on the equation set established by the above formula (1). It should be noted that, in the embodiment of the disclosure, the second included angle between the light source and the terminal may refer to an included angle between the light source and a plane where the warm display screen of the terminal is located, that is, θ in fig. 6 1 。
After the first included angle and the second included angle are determined, and then the light sensing model is established by combining the actual light-emitting brightness of the light source, in an embodiment, the included angle of the light source relative to the ground horizontal plane is determined according to the sum of the first included angle and the second included angle, and then the first light sensing model is established based on the actual light-emitting brightness of the light source. It should be noted that the first light sensation model may be a model obtained by training based on the included angles of the multiple groups of light sources with respect to the ground horizontal plane and the actual light-emitting luminances of the light sources, where the included angle of the light sources with respect to the ground horizontal plane corresponds to the actual light-emitting luminance of one light source, and is referred to as a group in the embodiment of the present disclosure.
In practical application, if an angle sensor is arranged in the electronic equipment providing the light source, the included angle between the angle sensor and the ground horizontal plane can be determined based on the angle sensor, the included angle is sent to the terminal disclosed by the invention, and the terminal can directly determine the actual brightness of the light source according to the first light sensation model, so that the display brightness of the display screen is adjusted.
FIG. 7 is an exemplary diagram of an angle between a light source and a ground level, as shown in FIG. 7, where the angle between the light source and the ground level is θ in an embodiment of the disclosure 1 +θ 3 。
In another embodiment, the second light sensation model may be established according to the second included angle, i.e., the included angle between the light source and the terminal, and based on the actual light emitting brightness of the light source. It should be noted that the second light sensation model may be a model obtained by training based on the included angles of the plurality of groups of light sources relative to the terminal and the actual light-emitting brightness of the light sources, where the included angle of the light sources relative to the terminal corresponds to the actual light-emitting brightness of one light source, and is also referred to as a group in the embodiment of the present disclosure.
In practical application, if the electronic device or the terminal providing the light source is provided with the positioning sensor, an included angle between the light source (the electronic device providing the light source) and the terminal can be determined based on the positioning sensor, the included angle is sent to the terminal disclosed by the disclosure, and the terminal can directly determine the actual brightness of the light source according to the second light sensation model, so that the display brightness of the display screen is adjusted.
It can be understood that, the present disclosure is based on a built-in angle sensor, and determines the first angle and the second angle in combination with the aforementioned scheme including the above formula (1) to determine the position of the light source (including the position of the light source relative to the terminal, or the position of the light source relative to the ground level), so as to establish a light sensation model for determining the actual light emitting brightness of the light source, which can enhance the capability of the terminal in automatic dimming and the like.
In one embodiment, a third optical sensor is included in the terminal, the third optical sensor is close to the back shell of the terminal, and the angle of view of the third optical sensor is towards the back shell of the terminal;
the method further comprises the following steps:
acquiring the ambient light brightness of ambient light outside the light source detected by the third optical sensor;
the determining the actual light-emitting brightness of the light source according to the brightness value of the light source detected by each optical sensor comprises:
and if the ambient light brightness is smaller than a preset brightness threshold, determining the actual light emitting brightness of the light source according to the brightness value of the light source detected by each optical sensor.
Since the light intensity of the light source sensed by the optical sensor is more likely to cause the aforementioned problem of detection deviation in a darker environment, the present disclosure uses the third optical sensor with the field angle facing the terminal back shell to detect the ambient light brightness of the ambient light outside the light source, and determines the actual light emitting brightness of the light source when the ambient light brightness is smaller than the preset brightness threshold, so as to improve the necessity of determining the actual light emitting brightness of the light source by using the scheme of the present disclosure.
It should be noted that, since the light source of the present disclosure includes a point light source or a line light source, and after the light of the point light source or the line light source is blocked, the light cannot pass through the blocking object, the ambient light detected by the third optical sensor in the present disclosure may be understood as light that does not include the light source.
